39 How Do We Proceed? We need to know our goals for preserving our collections. We need to know what the collections need to satisfy the goals for preserving the collections We need to consider in our long term planning the fact that as collections deteriorate they lose value and the costs to preserve increase We need to consider that the storage environment has the greatest potential to minimize preservation costs over the long term

40
40 We need to acknowledge that there are limitations to energy and to budgets We must weigh the competing demands for resources with our priorities We need to know how building architecture and environmental systems can work together in an interrelated and supportive manner to create the most cost effective storage environments for the collections we are preserving

41
41 We need to bring all these considerations together to engage in a dialogue, working as a team that includes engineers, architects, conservators, archivists, curators, project managers and others.
